What types of capacitors?

Based on the material characteristics of capacitors, they can be divided into the following categories: 1. Aluminum electrolytic capacitors have a capacitance range of 0.1uF--22000uF, the best choice for high pulsating current, long life, and large capacity. They are widely used in power supply filtering. , Uncle lotus root and other occasions. 2. The capacitance range of the film capacitor battery is 0.1pF-10uF, with small tolerance, high capacity stability and extremely low piezoelectric effect, so it is the first choice for X, Y safety capacitors and EMI/EMC. 3. The capacitance range of tantalum capacitor is 2.2uF-560uF, with low equivalent series resistance (ESR) and low equivalent series inductance (ESL). The pulsation absorption, transient response and noise suppression are better than aluminum electrolytic capacitors, which is an ideal choice for high-stability power supplies. 4. The capacitance range of ceramic capacitors is 0.5pF-100uF. The unique material and the crystallization of thin film technology cater to today's lighter, thinner and more energy-saving design concepts. 5. Super capacitor battery capacity range is 0.022F-70F, extremely high capacitance value, so it is also called gold capacitor or farad capacitor. The important features are: ultra-high capacitance value, good charge/discharge characteristics, suitable for electric energy storage and power backup. The disadvantage is that the withstand voltage is lower and the operating temperature range is narrow. Electrolytic capacitors can generally only be used within the range of -20°C to +70°C. The characteristics are greatly affected by temperature and frequency. Generally, aluminum electrolytic capacitors are often used. The type of aluminum electrolytic capacitor is generally CDXX, and the capacity, withstand voltage, and positive and negative poles are all marked on the shell. Sometimes it is also expressed by the length of the lead wire. The long wire is positive and the short wire is negative.
